B1.1.3 - Specialised Cells Flashcards
How is a nerve cell adapted to carry out its function (job)?
It is long and thin so can send messages all over the body.
It has connecitons at each end to connect with other nerve cells.
What is the funciton of the jelly layer on a human egg cell?
To attract sperm.
To protect the egg.
How is a sperm cell adapted to carry out its function (job)?
They have a streamlined shape, to help them swim.
They contain mitochondria to give energy to their tail.
They have a tail for movement.
They have a pointed head that can burrow into the egg.
What is the function (job) of a sperm cell?
To carry male genetic information.
To fertilise an egg.
How is a root hair cell adapted to carry out its function (job)?
It has a long, thin root hair which creates a large surface area for absorbing water and nutrients.
What is a specialised cell?
A cell that is adapted (has special features).
So that it can carry out a specific function (job).
What is the funciton of the fat stores in a human egg cell?
To provide energy for the developing embryo (early form of a baby)
What is the red pigment in red blood cells called that allows the cell to carry oxygen?
Haemoglobin
What is the function of a red blood cell?
They transport oxygen around the body.
How is a leaf cell adapted to carry out its function (job)?
It is long and thing which provides a big surface to capture sunlight.
It contains many chloroplasts which carry out photosynthesis.
Which type of specialised cell is this?
A nerve cell
What is the function (job) of a nerve cell?
To carry electrical impulses around the body.
What is the funciton of a root hair cell?
To help plants absorb nutrients and water from soil.
How are red blood cells adapted to carry out their function (job)?
They contain haemoglobin (red pigment) that joins with oxygen.
They have no nucleus so more room for oxygen.
They have a disklike shape to increase the surface area that oxygen can bind to.
Which type of specialised cell is shown below?
Root hair cell
What is the function of a leaf cell?
To carry out photosynthesis and make food for the plant.
